The U.S. Supreme Court granted certiorari in Cuozzo Speed Technologies, LLC v. Lee, U.S. No. 15-446 (cert. granted January 15, 2016). There are two issues in this case.
The first issue is in regards to the claim construction standard used during Inter Partes Review (IPR) proceedings before the Patent Trial and Appeal Board (PTAB). Currently, the PTAB construes the claims of an issued patent in an IPR proceeding according to their broadest reasonable interpretation. This standard is different than the “plain and ordinary meaning” standard used in federal district court. The question is whether or not the PTAB is using the correct claim construction standard, or if it the claims should be interpreted according to their plain and ordinary meaning.
The second issue is whether or not the PTAB’s decision to institute an IPR proceeding is judicially unreviewable. In Cuozzo, the Federal Circuit held that 35 U.S.C. 314(d) bars it from reviewing a PTAB decision to institute an IPR, even if the issue is raised in an appeal of a PTAB final decision.
